SPECIFICATION forming part of Letters Patent No. 374,941, dated December 20, 1887.

Application filed .August 13,1886. Serial No. 2l0,832.

To all whom it may concern.-

Be it known that I, WILLIAM M. COSTON, a citizen of the United States, residing at Gentralia, in the county of Nemaha and State of Kansas, have invented a new and useful Doubletree for a Riding or Walking Cultivator, of which the following is a specification.

The figure is a front View of my improved cultivatordoubletree.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved cultivator-doubletree which shall be so constructed as to furnish a place at the proper height from the ground to attach the front ends of the cultivator-beams, and having an arch in the center high enough to pass over corn, cotton, or other cultivated crops, and to get the plows as near the team as possible, and at the same time have the draft at the right height, as will be hereinafter fully described.

A A are the side bars of the frame, which are connected a little in front of the center by (No model.)

K K represent a metallic doubletree pivoted in the center by abolt passing through the tongue Dand front bar, 0, and a circular plate, R, secured to the under side of the tongue, and another corresponding one, B, secured to the upper side of the doubletree and holding the doubletree in an upright position and so that the ends may play back and forth. The doubletree bends downward at right and left of center, and then outward, forming a place for attaching the cultivator-beams L L, and then turns upward and is perforated with holes, in which to insert the singletree-hooks O 0, so that the draft may be rightly adjusted.

P P are the singletrees.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The doubletree K, having the arched central portion, the horizontal side sections for the attachment of the plow-beams, and the turned-up perforated ends for adjustable draft attachment, in combination with the fifth- Wheel plates R and the frame and tongue, substantiall y as shown and described.

WILLIAM M. GOSTON.
